.NET Hobbyist Programmer Staying Confused in a Busy World

The Mount St. Helens VolcanoCam has presented quite a few interesting pictures since it was activated in 1996.  It is interesting to see the weather in the area, and I have to make some adjustments for the three hour time difference.  The new webcam was installed in September 2004 in time to catch the eruption series that was soon to follow.  The website archive has the eruption series.

The March 08, 2005 Eruption Event Movie is described thusly:

The network connection to the VolcanoCam had failed the previous Friday and Forest Service telecommunications experts were hard-pressed to locate the failure point. All communications (telephone, computer and the VolcanoCam link) were down between the Coldwater Ridge Visitor Center and the Johnston Ridge Observatory, with the rest of the world. The network connection was restored around 1:30 pm PST.

Four hours later ...

A small explosive event at Mount St. Helens volcano began at approximately 5:25 p.m. PST. Pilot reports indicate that the resulting steam-and-ash plume reached an altitude of about 36,000 feet above sea level within a few minutes and drifted downwind to the east-northeast. The principal event lasted about 30 minutes with intensity gradually declining throughout. The USGS Cascades Volcano Observatory lost radio signals from three monitoring stations in the crater soon after the event started. The cause of the outage won’t be known until scientists can visit the crater tomorrow to assess the situation, weather permitting. The event followed a few hours of slightly increased earthquake activity that was noted but not interpreted as precursory activity. There were no other indications of an imminent change in activity.

The local VolcanoCam pictures are generally unimpressive, although it is evident there was some violence involved since some sensors were lost.  Distance shots (CNN Scientists seek source of Mount St. Helens blast, Fox News Mount St. Helens Releases Ash Plume, Rory and Aydika here) look much better since the ash cloud is nicely lighted by the setting sun.  I suspect CNN's scientists found their answer in the volcano's crater.

Of course, environmentalists do not want to hear that Mount St. Helens is the top polluter in Washington since they do not like pollution and cannot sue a volcano.
